Description

Technical Field

[0001] The present invention relates to the field of intelligent lighting control technology, and in particular to an intelligent lighting control system based on BLE and LoRa technologies. Background Art

[0002] Smart home lighting control system is an important part of smart home. It realizes the intelligent management of home lighting system. Smart home lighting control system adopts digital intelligent gateway, intelligent switch, intelligent socket and intelligent home remote control equipment to wirelessly control the switch and brightness adjustment of lights to realize the transformation of various lighting scenes. The system aims to improve the comfort and convenience of life while effectively saving energy.

[0003] Traditional lighting control systems mostly use wired connections or single wireless communication technology. This solution has the following shortcomings:

[0004] First of all, complex wiring is a major drawback of wired lighting control systems. During the decoration or renovation of a house, a large number of wires and cables need to be laid, which not only increases the difficulty and cost of construction, but may also have a certain impact on the aesthetics and structure of the house. At the same time, complex wiring also increases the difficulty of later maintenance and inspection. Once a fault occurs, troubleshooting and repair will become very cumbersome. Secondly, the use of a single wireless communication technology also has many limitations. On the one hand, the communication distance is limited, resulting in a limited range of lighting control, which cannot meet the needs of large or complex apartments. On the other hand, the stability and reliability of wireless communication technology are relatively poor, and it is easily affected by environmental factors, such as electromagnetic interference and signal attenuation, which affects the accuracy and timeliness of lighting control. In addition, a single wireless communication technology may also lead to high power consumption, increase household electricity costs, and may also cause a certain burden on the environment.

[0005] Therefore, it is necessary to design an intelligent lighting control system based on BLE and LoRa technology to solve the above problems. Summary of the invention

[0006] The purpose of the present invention is to solve the shortcomings of the prior art and propose an intelligent lighting control system based on BLE and LoRa technology.

[0007] In order to achieve the above object, the present invention adopts the following technical solutions:

[0008] An intelligent lighting control system based on BLE and LoRa technology, including the following modules:

[0009] Main control module: responsible for receiving lighting control instructions sent from the user's mobile device via BLE technology, parsing the instructions, and adjusting the switch status, brightness level, and color temperature parameters of the lights according to the instructions. At the same time, the main control module is also responsible for processing the environmental information from the sensing module and automatically adjusting the lighting settings accordingly;

[0010] BLE communication module: responsible for establishing and maintaining BLE connection and bidirectional data transmission. Users can send control commands to the main control module through the application on the mobile device, and can also receive status feedback or notifications from the main control module;

[0011] LoRa communication module: responsible for long-distance communication between the main control module and the remote server or other LoRa devices. Through the LoRa wide area network technology, the lighting control instructions are transmitted across physical distances, which is suitable for the remote monitoring and control needs of the smart home system;

[0012] Sensing module: Contains light sensors and human motion detectors, which are used to monitor indoor light intensity and changes in human activity environment in real time, convert the collected environmental information into electrical signals, and send them to the main control module for processing;

[0013] Execution module: According to the instructions of the main control module, it directly controls the switch of the lamps, adjusts the brightness and color temperature. The execution module is connected to the main control module via wired or wireless means.

[0014] As a preferred technical solution of the present invention, in the main control module, the main control module integrates a BLE communication module, which supports the low-power Bluetooth protocol to ensure a stable and fast communication connection with the user's mobile device. The main control module has data processing capabilities and can perform lighting control operations according to preset logical rules or user-defined lighting schemes. The main control module receives environmental perception information from the sensing module, including light intensity and human activity, and then automatically adjusts the lighting settings based on this information to adapt to different scene requirements and improve lighting comfort and energy utilization efficiency. At the same time, the main control module is also connected to the execution module by wire or wireless means to convey control instructions to the execution module to achieve control of the lamps.

[0015] As a preferred technical solution of the present invention, in the BLE communication module, the user sends lighting control instructions to the main control module through the application on the mobile device. These instructions are transmitted by the BLE communication module and can be received and parsed by the main control module to control the lights in the home. The BLE communication module also has compatibility and scalability, supports a variety of mobile devices and operating systems, and supports interconnection with other smart home devices. In terms of security, the BLE communication module adopts encryption technology and authentication mechanism to ensure the security and privacy of user data and control instructions during transmission.

[0016] As a preferred technical solution of the present invention, the main control module encapsulates the lighting control instructions sent by the user through the mobile device, adds communication protocols and verification information to ensure the integrity and accuracy of the instructions during the transmission process, and then the main control module sends the encapsulated instructions to the LoRa wide area network wirelessly through the built-in LoRa communication module. The LoRa wide area network is composed of multiple LoRa base stations and gateways. These base stations and gateways are responsible for receiving and forwarding instructions from the main control module to ensure that the instructions can be transmitted to the target device across a long physical distance. During the instruction transmission process, LoRa technology uses the spread spectrum communication principle to achieve the goal of long-distance communication at low power consumption. At the same time, the LoRa wide area network also has anti-interference capabilities and data error correction mechanisms, which can ensure stable transmission of instructions in complex environments and avoid data loss or bit errors.

[0017] As a preferred technical solution of the present invention, in the sensing module, a photosensitive element is used inside the light sensor, including a photoresistor or a photodiode. The resistance value or current output of these elements changes with the intensity of the light. When the indoor light irradiates the photosensitive element, the photosensitive element adjusts its resistance value or generates a corresponding current according to the intensity of the light. This change is then converted into an electrical signal. The electrical signal is amplified and conditioned by the built-in circuit of the sensor to ensure the stability and accuracy of the signal, and then sent to the main control module through an analog or digital interface. After receiving the electrical signal, the main control module analyzes it to obtain the current light intensity in the room and adjusts the brightness of the light accordingly. The human motion detector uses an infrared sensor or a microwave sensor to detect human activities in the room. When a human body moves within the monitoring range of the detector, the infrared radiation field or microwave reflection characteristics around the detector are changed. This change is also converted into an electrical signal. The built-in circuit of the human motion detector filters, amplifies and digitizes the electrical signal. The processed electrical signal is transmitted to the main control module through the communication interface. The main control module determines whether there is human activity in the room according to the change of the signal, and triggers the corresponding light control logic accordingly.
